style="text-indent:25px">流量計(jì)可以水平和垂直安裝，但是應(yīng)該確保避免沉積物和氣泡對測量電極的影響，電極軸向保持水平為好。垂直安裝時(shí)，流體應(yīng)自下而上流動(dòng)。電磁流量計(jì)內(nèi)的測量電極處于一個(gè)直流或交流電場內(nèi)，如果其環(huán)境不能有效地被屏蔽于一個(gè)無干擾的條件下，對測量有嚴(yán)重干擾。傳感器外殼接地與否，直接關(guān)系到測量的精度和穩(wěn)定性，接地導(dǎo)線必須不傳任何干擾電壓，因此電磁流量計(jì)要求有非?？煽康慕拥?，要做好接地屏蔽，否則就會(huì)產(chǎn)生干擾電流。超聲波流量計(jì)也是比較常見的流量計(jì)，它的安裝在所有流量計(jì)的安裝中是簡單便捷的，只要選擇一個(gè)合適的測量點(diǎn)，把測量點(diǎn)處的管道參數(shù)輸入到流量計(jì)中，然后把探頭固定在管道上即可。</p><p style="text-indent:25px">渦輪流量計(jì)工作原理：在一定的流量范圍內(nèi)，渦輪的轉(zhuǎn)速與流體的流速成正比。流體流動(dòng)帶動(dòng)渦輪轉(zhuǎn)動(dòng)，渦輪的轉(zhuǎn)速轉(zhuǎn)換成電脈沖，用二次表顯示出數(shù)據(jù)，反應(yīng)流體流速。工作特點(diǎn)：①抗雜質(zhì)能力強(qiáng);②抗電磁干擾和抗振能力強(qiáng);③其結(jié)構(gòu)與原理簡單，便于維修;④幾乎無壓力損失，節(jié)省動(dòng)力消耗。容積式流量計(jì)工作特點(diǎn)：①計(jì)量精度高;②安裝管道條件對計(jì)量精度沒有影響;③可用于高粘度液體的測量;④范圍度寬;⑤直讀式儀表無需外部能源可直接獲得累計(jì)，總量，清晰明了，操作簡便;⑥結(jié)構(gòu)復(fù)雜，體積龐大⑦不適用于高、低溫場合;⑧大部分儀表只適用于潔凈單相流體;⑨噪聲和振動(dòng)較大。渦輪流量計(jì)垂直安裝時(shí)流體方向必須向上。</p><div
